RAZOR sTJaoie.

Application filed July 31, 1920, Serial 1%. 400,566. Renewed July. 10, 1922. Serial No. 573,922.

To all whom it may concern:

Be it known that I, EDGARD SGHUMANN, engineer, a citizen of the German Republic, residing at Berlin- Wilmersdorf, Homburgerstrasse 27, Germany, have invented certain new and useful Improvements in Razor Strops (for which I have filed application in Germany March 4, 1919), of which the following is a specification.

This invention relates to a stropping device for double-edged razor blades, in the case of which the blade is secured or fixed in a device and moved to and fro along a strop. In accordance with this invention, the device consists of a plate of sheet metal, the lower portion of which is formed to constitute a handle, while its upper portion is curved in such a manner that the blade, when in serted, will protrude from two slots oppositely disposed at a suitable distance from each other in the said curved portion. The blade, while in this position, is pressed toward the crown of the bend where it is secured by means of hooks engaging the apertures formed in the blade, so that this latter will bear up against the faces of the afore-' said slots disposed in the direction of the hooks, while underneath the blade there remain slits through which the strop may be passed. The stropping or honing of the blade is effected by moving the device to and fro. This improved stropping device distinguishes itself from the. onespreviously known by the feature that no additional parts or members are required for securing the blade. By means of this novel device, even entirely unskilled persons will be enabled to successfully strop a razor blade as re uired.

n embodiment of the subject matter of my invention is shown in-the accompanying drawing, in which:

Fig. 1 is a side View,

Fig. 2 another side View,

Fg. 8 a view from below,

Fig. 4 a perspective view showing the device when in use.

The device consists of a small plate of sheet metal, shaped at a to constitute a handle. The curved portion 6, adapted to support the blade, is provided with two oppositely disposed slots 0, arranged at such a distance from each other that the cutting edges of the blade e will slightly protrude therefrom. The blade is secured in its position by being suspended to two hooks f stamped or otherwise pressed out of the The stropping operation is effected, as illustrated in Fig. 4, by the device being moved to and fro along the strop drawn through the slots; the device being held in-such a'position relatively to the strop, that the cutting edge of the blade disposed forwardly relatively to the direction in which the stropping motion is carried out (indicated by the arrow in Fig. 4), will be lifted off from the These latter admit so much Specificationof Letters Patent.

strop, i. e., will be. inclined upwards. The I result is that the lower cutting edge of the bladeand this is a fact of substantial i111- portancewill bear against the strop with its entire surface. During the return motion of the device, the strop acts on the upper edge of the blade. The advantage re sulting is that the blade is honed or stropped while bent, in the manner known per se, since the strop will thus be able to adapt itself to an improved degree to the cutting edges of the blade. I

I claim; 1

A stropping device for flexible safety razor blades, comprising a curved sheet having a handle, and also having a pair of spaced slots to receive and expose the cutting edges of the blade, and means 011 the concave side of the. sheetto engage and hold the intermediate portion of the blade in l spaced relation to the sheet, the width of said slots being suflicient to permit the passage of a stop therethrough, in contact with the blade.

In testimony whereof-I have hereunto set my hand 1n presence of two SLlbSQllblIlgjWltnesses.
